This stores errno, the cancelation flags, and related bits for each thread
and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable!
Make libpthread dlopen'able by moving the cancelation wrappers into libc
and doing locking and fork/errno handling via callbacks that libpthread
registers when it first initializes. 'errno' *must* be declared via
<errno.h> now!
Clean up libpthread's symbol exports like libc.
On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec.

still specified snprintf() and vsnprintf() based on earlier drafts.
Allows snprintf() and vsnprintf() to be used when _XOPEN_SOURCE is
defined as 500. OK guenther@
actually remove this header. It was originally added for ports, which is
malloc.h-free now.

the b* byte functions belong in strings.h, not string.h so break
them out of string.h into a new strings.h. As long as there is no
POSIX or X/OPEN define in use string.h will pull in strings.h.

This version of the function will always open the secure/shadow/master
password files. Soon, the regular variants of these functions will not.
(Intermixing shadow and regular gets a little weird; don't do that.)
Not using struct spwd and getspwnam functions to reduce churn in callers.
Should just be a one line diff in most places.

thrkill(2), rolling the kill(2) syscall number with the ABI change to
avoid breaking binaries during during the transition. thrkill(2) includes
a 'tcb' argument that eliminates the need for locking in pthread_kill()
and simplifies pthread_cancel(). Switch __stack_smash_handler() to use
thrkill(2) and explicitly unblock SIGABRT.
Minor bump to both libc and libpthread: make sure you install a new kernel!

which results in tame() code placements being much more recognizeable.
tame() can be moved to unistd.h and does not need cpp symbols to turn the
bits on and off. The resulting API is a bit unexpected, but simplifies the
mapping to enabling bits in the kernel substantially.
vague ok's from various including guenther doug semarie
wrapper .h files and asm labels to let internal calls resolve directly and
not be overridable or use the PLT. Then, apply that framework to most of
the functions in stdio.h, string.h, err.h, and wchar.h. Delete the
should-have-been-hidden-all-along _v?(err|warn)[cx]? symbols while here.
tests clean on i386, amd64, sparc64, powerpc, and mips64

- MATH_ERRNO, MATH_ERREXCEPTION and math_errhandling
- Optional FP_FAST_FMA{,F,L} macros if fma() executes as fast or faster
than (x * y) + z; which in practice is achievable if gcc implements
__FP_FAST_FMA{,F,L}
